the submission is fast but I'm not sure how long to get included on the list I submitted my sites and blogs but none of those didn't get in.
Why submit to Yahoo as Bing has already taken over as the organic search results for Yahoo? You might want to submit to Bing instead.
If you mean Yahoo search engine, then you should place the links to your site on the other sites instead. If you mean Yahoo directory, then it may be wise to read Yahoo directory submission guidelines.
